APPARATUS FOR DRAWING WATER FROM CISTERNS.

Specification of Letters Patent.

Patented Jan. 8, 1907.

Application filed May 16, 1906- Serial No. 317,059.

To all whom, it may concern:

- Be it known that I, TIMOTHY LYDoN, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Apparatus for Drawing WVater fromCisterns, of which the following is a specification.

My invention relates to improvements in an apparatus for drawing waterfrom cisterns.

One object of the invention is to provide improved devices to be used inconjunction with a pump for drawing water from cisterns or tanks bywhich the water may be drawn from or near the surface or water-level,although the depth of water in the cistern or tank may vary.

Another object of the invention is to provide a device whereby the Watermay be drawn by the pump from the extreme lowermost point of thecistern, so that the dirt and sediment which accumulates at the bottomof such receptacles may be drawn off without the necessity of drainingthe receptacle.

Another object of the invention is to provide a construction whereby thelowermost outlet or sediment draw-off from the cistern maybe closed whenit is desired-to draw clear water.

The accompanying drawings illustrate the invention, in which Figure 1shows a vertical sectional view of the apparatus and the cistern. Fig. 2is a detail view of the sediment-cut-oifdevice, and Fig. 3 illustrates asectional view through one of the valves.

The drawings illustrate one form of construction for carrying theinventive idea into practical effect without, however, limiting theinvention to the particular construction shown.

Referring to the drawings by numerals, 1 designates a cistern, tank, orother receptacle, having an inlet-pipe 2 through which the water mayflow into said tank and also having an outlet-pipe 3, with a pump 4 ofany suitable construction at the upper end. The lower end of theoutlet-pipe 3 in the present instance is seated in a socket ordepression 5 at the bottom of the cistern or tank and at the upper endthe pump and outlet-pipe are supported by a stand 6, so as to berevolved.

At the lower end and immediately above the bottom 7 of the cistern ortank the outletpipe is provided with laterally-projecting branch Pipes8, which are provided in their lower sides with a plurality oferforations 9 which open downward and in c ose proximity to the saidbottom 7.

One of the objects of this invention is to providedevices that Wlllenable water and sediment to be drawn ofi entirely from the bottom ofthecistern in order to clean the latter, and duringthis-operation all otheropenings into the discharge-pipe from the cistern will be closed. Inorder'to accomplish this, I provide a valve device at the lower end ofthe dischargeipe, which in the present instance has the fbrm of apistonvalve 10, with a stem 11 extending vertically at the center ofsaid pipe. A link 12 has one end pivotally connected to the upper end ofthe stem, and the other end of said link is connected to a crank onhorizontal stem 13,

which projects into the discharge-pipe and which 1s carried on arevoluble plate 14 on the exterior of the said outlet-pipe. An arm 15projects laterally from the plate 1 1, and

said arm is provided with a slot 16 in its outer end.

An operating-rod 17 runs parallelwith and at the side of theoutlet-pipe, and the upper end of this rod terminates at a point withinconvenient reach at the side of the pump 4. This rod is sustained bypassing through bearings 18, which are clamped about the outlet-pipe,and the vertical position of the rod is such that it will lie at oneside of the slotted arm 15 on the plate 14, and a pin 19 projects fromthe rod 17 and through the slot 16 of said arm, so that the arm may bemoved vertically with the rod. The vertical movement of the rod and arm15 will cause a like movement to the piston-valve 10, so the latter maybe moved in the outlet-pipe to a point above or below the inlet ends ofthe branch pipes 8 at the bottom of the cistern.

Above the plate 14 the outlet-pipe 3 is provided with a plurality ofvalves 20 and 21 each of which comprises a stationary plate 22, having aport 23 and a movable plate 24, with an operating-arm 25. Each movableplate 24 is provided with a port 26. The arms 25 are also provided withslots 27, and pins 28 project from the rod 17 and enter these slots,so'that all the arms 25 and 15 of the valves are connected to theoperatingrod 17.

It will be noted that the ports 23 and 26 in valve 20 normally have aslightly different position with respect to each other than the terthrough such opened valve.

same ports in valve 21. The ports in the latter valve are normallyfarther apart, so that the movable plate of valve 21 will have to travelfarther to cause its two ports to register than the plate of valve 20.The object of this is to insure that only one valve will be opened at atime. By slightly depressing the rod 17 the upper valve 20 will beopened, and while the plate of the next lower valve will move its portswill not be opened until the rod has been depressed far enough to closethe ports in the upper valve.

By pushing the rod all the way down both valves 20 and 21 will be closedand the pistonvalve 10 will move down below the inlet ends of the branchpipes 8 and establish commu nication between them and the outlet-pipe 3.

It will thus be seen that by operating the rod 17 the piston-valve 10may be opened, so that when the pump is operated the water and dirt atthe bottom of the tank or cistern willbe drawn through the perforatedbranch I pipes up through the pipe 3 and discharged at the pump, and inthis manner the dirt may be readily removed from the bottom of thecistern or tank. When it is desired to draw clear water, the rod 17 willbe raised, so as to first close the piston-valve 10 and open one or theother of the upper valves, according to the height of the water in thecistern, and the operation of the pump will draw Wa- By mounting thepump on the stand 6 the entire apparatus may be revolved, so that duringthe cleaning operation the branch pipes 8 may be made to pass over theentire bottom surface of the cistern and draw the dirt'therefrom.

. Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In an apparatus for drawing water from cisterns the combination witha draw-off pipe having a plurality of draw-off passages in its lower endadjacent the bottom of the cistern, of a valve in said pipe to controlthe said bottom draw-ofi passages; a valve in said pipe above thedraw-off passages means whereby said valves may be opened one at a time,and

a pump connected to the draw-off pipe.

2. In an apparatus for drawing water from cisterns the combination witha draw-off pipe having an inlet near its bottom and another inlet abovethe bottom inlet, of means for governing said inlets; means forpermitting the outlet-pipe to be revolved means carried by theoutlet-pipe and projecting laterally therefrom and adjacent to thebottom of the cistern for directing the sedimentin the cistern towardtheoutlet-pipe, and a pump connected to the outlet-pipe.

3. In an apparatus for drawing water from.

4. In an apparatus for drawing water from cisternsthe combination with adraw-off pipe, of branch pipes carried by the draw-off pipe and openinginto the latter and provided with a plurality of perforations; a valvein the draw-off pipe to control the passage of water and sediment fromthe branch pipes a valve in the draw-0E pipe above the branch pipes forthe passage of clear water; means connecting said two valves wherebytheymay be opened and closed successively; and a pump connected to thedraw off pipe' 5. In an apparatus for drawing water from I cisterns thecombination with a draw-off pipe, of a perforated branch pipe carried bythe draw-off pipe and opening into the latter and projecting laterallyadjacent the bottom of the cistern a valve to control the passage in theperforated pipe; a valve in the drawoff pipe above the branch pipe; ar0deXtend-.

ing parallel with the draw-off pipe and con nected to said valves a pumpconnected to said draw-off pipe; and means for sustaining said pump anddraw-off pipe so they maybe revolved.

In testimony whereof I affix my signature in presence of two witnesses.
